Description

Technical Field

[0001] The present invention relates to the field of pharmaceutical technology, and particularly relates to a substituted bis(pyridin-2-yl)amine derivative, a pharmaceutically acceptable salt, solvate, stereoisomer, prodrug, pharmaceutical composition thereof, and its medical use. Background Art

[0002] The cyclin-dependent kinase (CDK) protein family consists of members that are key regulators of the cell division cycle involved in the regulation of gene transcription (transcriptional CDK) (cell cycle CDK) and members with other functions. CDK requires activation by binding to a cyclin regulatory subunit. The cell cycle CDKs CDK1 / cyclin B, CDK2 / cyclin A, CDK2 / cyclin E, CDK4 / cyclin D, and CDK6 / cyclin D are successively activated to drive cells into and through the cell division cycle. The transcriptional CDKs CDK9 / cyclin T and CDK7 / cyclin H regulate the activity of RNA polymerase II by phosphorylation of the carboxyl-terminal domain (CTD).

[0003] CDK9 is the catalytic subunit in the positive transcription elongation factor b (P-TEFb) complex, regulates the transcriptional elongation of genes by phosphorylating the carbon-terminal region of RNA polymerase II, and is a kinase that regulates RNA transcriptional elongation located at chromosome 9q34.1. The CDK9 kinase is highly expressed in cardiomyocytes, hepatocytes, hematopoietic tissues, adipocytes, neurons, and muscle cells, and is generally highly expressed in tumor cells. CDK9 is also an important factor in tumor cell progression and maintenance. CDK9 is widely expressed in a variety of eukaryotic cells and human tissues. CDK9 inhibitors promote apoptosis of cancer cells by inhibiting the transcriptional elongation of genes to down-regulate the expression of related oncoproteins (MYC) and the expression of the apoptosis inhibitor protein Mcl-1. CDK9 inhibitors reactivate silenced genes by regulating the epigenetic factor BRG1, including the activation of ERVs in tumor cells, promote interferon expression, and make tumor cells more sensitive to immunotherapy.

[0004] Currently, several companies are developing CDK9 inhibitors, including the selective CDK9 inhibitor BAY1251152 developed by Bayer, the selective CDK9 inhibitor AZD4573 developed by AstraZeneca, the non-selective CDK9 inhibitor TP-1287 developed by Tolero, and the non-selective CDK9 inhibitor QHRD107 developed by Changzhou Qianhong Pharmaceutical Co., Ltd. However, most of the current selective CDK9 inhibitors are still in the early stage of clinical development. Among these drugs in clinical research, BAY1251152 has high toxicity and is administered by injection. The kinase selectivity and metabolism of AZD4573 are not good, restricting its better efficacy. Therefore, it is of important clinical significance to develop new highly active and highly selective CDK9 inhibitors that meet the clinical medication needs and improve patient compliance.

[0361] The working concentrations of the components in the Test group for different kinase reactions were as follows:

[0362] Compound: Dissolve the compound to be tested at 10 mM at room temperature and perform gradient dilution with DMSO, and then dilute it with deionized water to a 4x compound working solution with the DMSO content being 2%. The highest concentration of the compound used in the CDK1 and CDK2 tests is 10 μM, and for CDK9 it is 1 μM.

[0363] 1.33x Reaction Buffer: Composed of 26.7 mM MOPS, 6.67 mM MgCl 2 and 0.0133% Tween-20. After preparation, store it in the refrigerator at 4 °C in the dark. Add freshly prepared DTT to a final concentration of 5.33 mM before use.

After the incubation, use the Victor X5 fluorescence microplate reader from PerkinElmer to read the signal. The excitation wavelength is 320 nm, and the emission wavelengths are 615 nm and 665 nm. The method for calculating the inhibition rate is as follows:

[0369] 1. Calculate the value of 665 nm / 615 nm (hereinafter referred to as the Ratio value) for all groups, and calculate the inhibition rate based on the Ratio value of each group;

[0370] 2. Inhibition rate = (PC Ratio – Test Ratio ) / (PC Ratio – Blank Ratio ) * 100%;

[0371] 3. Use XLFIT 5.0 software (IDBS, UK) for fitting. Use the logarithm of the compound concentration as the X-axis and the inhibition rate as the Y-axis, and use the four-parameter model to calculate the half-maximal inhibitory concentration IC 50 .

[0383] Experimental protocol:

[0384] Test animals: Healthy adult male ICR mice (weight 30 - 40 g, 12 mice in the intragastric administration group were fasted overnight and allowed free access to water and food 4 h after administration), provided by Beijing Vital River Laboratory Animal Co., LTD;

[0385] Route of administration and dosage: ICR mice were administered by tail vein gavage (10 mg / kg, 5% DMSO, pH 4.5 20% Captisol).

[0386] Blood sample collection: Animals meeting the experimental requirements were selected and weighed and marked before administration. Before collecting blood samples, the mice were restrained. For each mouse administered, at the predetermined blood collection time points (gavage administration: blood was collected at 0.083, 0.25, 0.5, 1, 2, 4, 6, 7.5, 24 h after administration, a total of 9 time points), approximately 100 μL of blood was collected by orbital bleeding.

[0389] Test Example 4: In vivo efficacy experiment

[0390] The in vivo efficacy experiment was carried out on BALB / c nude mice subcutaneously implanted with a xenograft (CDX) of a human tumor cell line derived from MV4-11 acute myeloid leukemia patients.

[0391] Experimental protocol: BALB / c nude mice, female, 6 - 10 weeks old, weighing about 20 - 23 g, were kept in a special pathogen-free environment and in single ventilated cages (4 mice per cage, 2 cages per group, 8 mice in total). All cages, bedding, and water were disinfected before use. All animals had free access to standard certified commercial laboratory diets. A total of 85 mice purchased from the Experimental Animal Business Department of Shanghai Institute of Planned Parenthood Research (No. 3577 Jinke Road, Pudong, Shanghai) were used for the study. Each mouse was subcutaneously implanted with tumor cells (1×10 7 0.1 ml + Matrigel 0.1 ml) for tumor growth. When the average tumor volume reached approximately 165 cubic millimeters, administration began. The test compound was administered by oral gavage daily at a dose of 10 mpk. The anti-tumor efficacy was determined by dividing the average tumor increased volume of the animals treated with the compound by the average tumor increased volume of the untreated animals.

[0392] The tumor volume was measured twice a week with a two-dimensional caliper, and the volume was measured in cubic millimeters. Tumor volume TV = 0.5a × b 2Among them, a is the long diameter of the tumor, and b is the short diameter of the tumor.

[0393] Relative tumor growth rate T / C(%), that is, at a certain time point, the percentage value of the relative tumor volume of the treatment group and the control group. The calculation formula is as follows: T / C% = T RTV / C RTV ×100% (T RTV : average RTV of the treatment group; C RTV : average RTV of the vehicle control group; RTV = V t / V 0 ,V 0 is the tumor volume of the animal at the time of grouping, and Vt is the tumor volume of the animal after treatment).

[0394] The weight change (%) of the tumor-bearing animals is calculated as follows: (weight at measurement - weight at grouping) / weight at grouping × 100.

[0395] The effect of compound Z-1 on the tumor volume of animals is specifically as Figure 1 shown, and the relative tumor growth rate is specifically as Figure 2 shown. Figure 1 and Figure 2 The data in show that compound Z-1 exhibits a significant effect of inhibiting tumor growth and has anti-tumor efficacy.
